To all whom/.it may concern: Y

Be it known that we, OLE SWENSON aud WILLIAM SWENsoN, of Cresce, in the countyv of Howard and State of Iowa, have invented a new and Im proved Hay-Loader, of which the` followlng is a full, clear, and exact descrip-- tion.

Our invention relates to an improvement in hay-loaders, and it has for its object to provide a hay-loader in which the body or elevator will be narrow at the top and the feed at the top be faster than that at the bottom.

Another object of the invention is to provide a means whereby the rake and the elevator of the hay-loader will rise simultaneously upon meeting an obstruction, and whereby also the rake may be elevated independ ently of the body or elevator of the loader when occasion may demand.

A further object of the invention is to so hang the body or elevator of the hay-loader that it may be raised from the wagon in which the hay is to be delivered, and whereby also the said elevator may be expeditiously and conveniently lowered from the ground and the pitch regulated.

Another object of lthe invention is toprovide a novel and simple means for throwing the elevator in and out of gear with a groundwheel of the machine. Y

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views.

Figure 1 is a plan View of the hay-loader. Fig. 2 is a longitudinal vertical sectionk taken on the line 2 2 of Fig. 1. Fig, 3 is a section taken substantially on the line 3 3 of Fig. 2, and Fig. 4. is a section taken practically on the line l 4 of Fig. 3.

In carrying out the invention, what maybe termed the frame or carriage of the machine consists of a cross-bar 10, from which hangers or standards 11 are downwardly projected, and to each standard or hanger at its lower end a short axle 12 is secured, upon the outer end of which a ground-wheel 13 is jouras shown in Fig.`2.

tary shaft B atthe base of the elevator.

naled, and a yoke 10el is secured to the said standards, being forwardly and horizontally projected, and said yoke is attached in any suitable or approved manner to the tongue or pole 10b, which may be and preferably is providedl with a hook for attachment to a wagon in which the hay is to be loaded.

v The elevator A consists of a body comprising a floor 14 and side pieces l5, and the body 'of the said elevator is made tapering, being ends of the shaft, and in the slotted portions of the upper standards 17 a rock-shaft C is journaled, the crank-arms 20 whereof correspond in number to the crank-arms of the ro- The crank-arms 20 of the upper shaft O between the sides of the body of the elevator are full arms, while the arms 21 at the extremities of this Shaft are simply quarter-cranks.

Each full crank-arm 2O has pivotally secured thereto a yoke 22, and the quarter-crank at each end of the upper or rock shaft C is 'connected by a pitman 23 with the smaller crank-arms 19 at the ends of the lower rotary crank-shaft B.

An elevator-arm D, consisting of a bar, is

lpivotally attached to each crank-arm 18 of the lower rotary crank-shaft B, and is likewise pivotally connected with a yoke 22 of a corresponding, crank arm on the upper rock crank-shaft C, as is best shown in Fig. 1; and the said elevator-arms D are of a length substantially that of the body of the elevator, or practically so. Each elevator-arm is provided 'upon its lower face with'series of Vteeth 24, and

at the lower end of each elevator-arm a hookshaped tooth 25 is attached to its under face, and these teeth, as shown in Fig. 2, extend rearwardly beyond the arms.

- The rock crank-shaft C is held in its bear- IOO ings and yet permitted to adjust itself to the bulk of hay upon the elevator by causing springs 26 to have constant bearing on the shaft at the standard 17, in which it is journaled, the said springs being preferably secured to the side boards 15 of the elevator.

The elevating arms are rotated preferably from the right-hand axle of the frame, and the connection is substantially as follows: A chain-wheel 27 is loosely mounted upon the hub of the right-hand ground-wheel, as shown in Fig. 3, being prevented from slipping therefrom by means of a flange 28, formed on the said hub; and the chain wheel 27 has a ratchet-wheel 29, formed upon its inner face around the hub of the ground-wheel, as shown in Fig. 4, the teeth of the ratchet-wheel being internally placed. These teeth are normally engaged by a spring-pressed dog 30, also best shown in Fig. 4, and likewise in Fig. 3, and this dog is pivoted upon the hub of the groundwheel. Therefore, normally, the chain-wheel will turn with the right-hand ground-wheel; but it may be made to turn loosely on the hub of this ground-wheel through the medium of a shifting device, which preferably consists of a conical bushing 31, mounted to slide on the right hand axle l2, and is operated through the medium of a shifting-lever 32, engaging near its upper end with recesses in a rack 33, secured to the frame or carriage of the machine. lVhen this shifting-bushing is out of engagement with the dog 30, the chainwheel and right-hand ground-wheel will move together; but when the bushing is forced outward it will ride upon the spring-controlled end of the dog and compress that end, therefore carrying the opposite end out of contact with the teeth of the ratchet-wheel 29. Consequently at this time the chain-wheel will not be operated by the ground-wheel, and the elevating-arms will not be operated.

A grooved pulley 34 is journaled upon the upper end of the right-hand bracket 16 of the elevator, and a small chain-wheel 35 is secured upon the right-hand extremity of the lower or rotating crank-shaft B, while a driving-chain 36 is made to pass over the large chain-wheel 27 around the pulley 34 and engages with the smaller chain-wheel on the said lower shaft B. The driving-chain engages with the upper peripheral surface of this wheel.

Owing to the upper shaft C being a rockshaft and the lower shaft B a rotating shaft, at each forward or rearward movement of the upper crank-arms 20, the elevator-arms will be given a full movement, either forward or rearward, and the hay will consequently be fed faster at the upper or contracted end of the elevator than at the base or wider portion, and owing to this fact the elevator may pe safely and successfully given this tapering orm.

The elevator is supported from the carriage in a peculiar manner. It is provided at each side of its base portion with an upwardlyextending hanger 37, preferably inwardly curved at its upper end in order that the hangers may be hung upon the inner ends of the axles l2. Each elevator-hanger 37 is provided with a longitudinal slot 38, through which the axle passes. Therefore, when the elevator meets with any obstruction at its base it will ride upward automatically to clear the same, and even when so doing or when the elevator is being raised or lowered the driving-chain 36 vill remain stretched and operative. Furthermore, this peculiar mounting of the elevator on the carriage er1- ables a person standing upon the load or upon the vehicle to be loaded to readily elevate the upper end of the elevator.

A rake E is located at the rear of the ele- Vator, and the head 39 of the rake is pivotally mounted in the upper ends of the elevatorhangers 37. Consequently, when the lower end of the elevator is raised for any purpose the rake will be likewise elevated.

A rearwardly and downwardly curved bracket 40 is projected from each end of the rake-head, and a tension-bar 41 is pivoted in the rear ends of these brackets or arms 40, being provided at one or at both ends with an attached spring 42, the said spring being likewise secured to the head, and the spring so acts that when the tension-bar is rotated upwardly and forwardly and tension is removed therefrom the spring will cause the said bar to turn backward to its normal position, and when in this position a series of eyes 43, secured ou the tension bar, will be in horizontal position.

The rake-teeth 44 are of a spring material, as is usual, and are curved in the customary manner, each tooth being passed through one of the eyes 43. Therefore, when a tooth or a series of teeth is forced upward said tooth or teeth will carry the eyes 43, through which they pass, in the same direction, and the ten- Sion-bar 4l will be forwardly rotated, and as soon as the obstruction whichforced the teeth upward is passed the bar will restore the teeth to their normal position.

The rake is raised or lowered by means of a lift-lever 45, mounted upon the cross-bar l0 of the frame and provided with the usual latch-lever and rack. The lift-lever is usually of the elbow pattern, and its forward member is adjustably connected by a rod 46 with an arm 47, forwardly projected from the central portion of the rake-head. A shield 48 is pivotally connected with each side board of the elevator at its base, and the shields are adapted to trail upon the ground and are also supported. by cables or chains 49, attached to them and to the outer eyes on the rake. These shields prevent the hay from being drawn into the wheels and likewise facilitate the hook-teeth at the bottom of the elevator-arms grasping the hay; and these hook-teeth, two of which are usually placed upon each'elevator-arm, materially assist in quickly delivering the hay from the rake to the elevator, since they are capable of carrying forward large bunches.

The elevator is given desired inclination through the medium of a bar 50, pivoted upon the pole l0b or the yoke 10a, the bar having a series of notches 5l produced in its under edge at its free end, and the notched portion of the bar is made to pass through a keeper 52, secured to the central under portion of the elevator-body. A cord or chain 53a is secured to the elevator-body forward of the keeper 52, and is passed around a pulley 53, located in an eye formed at the free end of the notched bar 50, the said cord or chain being then passed over a pulley 5t above the keeper 52, and thence downward over suitable guide-pulleys 55, located at the junction of the bar and the frame. Under this construction it will be observed that the elevator will be raised or lowered conveniently and easily from the ground.

Having thus described our invention, we claim as new and desire to secure by Letters Patentl. In a hay loader, a tapering elevator having slotted bearings at its contracted end, a

rock shaft provided with crank arms jour naled in said bearings, springs normally holding the shaft in its bearings, permitting the shaft to adjust itself to the amount of hay on the elevator, a rotatable crank shaft j ournaled near the base end of the elevator, elevator arms pivotally connected with the corresponding crank arms of the two shafts, and a driving connection between the rotatable shaft and the rock shaft, as and for the purpose set forth.

2. In a hay loader, the combination with an elevator having slotted bearings at its upper end, of a rock shaft journaled in said bearings and provided with crank arms, springsV engaging the rock shaft and holding it in the said bearings, yokes pivoted on the cranks of the said shaft, a rotatable crank shaft jour-v naled near the base or lower end of the elevator, elevator arms pivotally connected with the crank arms of the rotatable shaft and with the yokes of the rock shaft, a driving connection between the said shafts, and means for operating the rotatable shaft, substantiallyv as described.

3. In a hay loader, the combination with the drive wheels, and their axles, of an elevator having its lowerv end loosely suspended from the axles, and provided with reciprocating feed arms, and means for operating the feed arms from one of the drive wheels, substantially as described.

4. In a hay loader, the combination, with the carriage thereof, and the elevator, of slotted hangers connecting the carriage with the elevator, whereby the said elevator may have movement on the said carriage to clear an obstruction, as and for the purpose set forth.

5. In a loader, the combination, with a carriage and the elevator thereof, of a slotted hanger secured at each side of the base of the velevator and loosely mounted on the axle of the carriage, the axle passing through the slots of the hangers, as and for the purpose set forth.

In a hay loader, the combination, with the carriage and the elevator, of slotted hangers attached to the elevator, by means of which the elevator is mounted upon the carriage, and a rake pivotally connected with the said hangers, whereby the rake and the elevator will be simultaneously raised in passing lan obstruction, as and for the purpose specified.

7. In a hay loader, the combination with a supporting frame, axles carried by the frame, drive wheels on the axles and a sprocket wheel mounted on the hub of one of the drive wheels and having a pawl and ratchet connection therewith, of an elevator having slotted hangers at its lower end through which the axles pass, crank shafts mounted in the elevator, feed arms pivotally connected with the crank shafts, a sprocket wheel on the lower shaft, a guide pulley, and a chain passing around the guide pulley and sprocket wheel of the drive wheel and over the sprocket wheel of the crank shaft, substantially as described.
